I think I've finally decided to break into my motor and need some help.
I ride trails, dunes and like to drag. Running open air box, hrc cam, sparks pipe.
With that said, I am confused which way to go on the piston.
I would assume that the 500cc pistion with the 12:1 compression would produce more horsepower than the 450cc 13:1 piston.
I could really use some input on the pros and cons of going either way. In addition to the piston, I will likely have the head ported and polished and a 3-way valve grind done.
I've looked at a number of the 13:1 posts and hear really good things about that mod, but am unclear if the 500 kit is the way to go.
THANKS IN ADVANCE !!!!!!!!!!!!!!!!!!!
